Safe Use of Platforms Flashcards

What type of activities should NOT be performed from a tower scaffold platform?

Answer: Hot work (welding, cutting) without a specific risk assessment and fire precautions, or pulling heavy loads that could overturn the tower

Hot work creates fire risks (aluminium towers conduct heat, platforms can ignite). Pulling heavy loads or applying significant horizontal forces can overturn the tower. These activities require specific risk assessments, additional precautions, or alternative access equipment.

What is the importance of distributing the load evenly across the platform?

Answer: Uneven loading shifts the centre of gravity to one side, increasing the overturning moment and reducing stability on that side

Concentrated loads on one side of the platform shift the centre of gravity towards that edge, increasing the overturning moment on that side. Materials should be spread evenly across the platform to maintain a balanced, centred centre of gravity.

What is the role of the 'ground person' when a tower scaffold is in use?

Answer: To control access to the tower, keep the area clear, pass up materials, and be ready to summon help in an emergency

The ground person (banksman) controls access to the tower base, maintains the exclusion zone, passes materials up as needed, monitors weather conditions, and is prepared to raise the alarm and summon emergency assistance if an incident occurs.

Can a tower scaffold be used as a loading platform for hoisting materials to a higher level?

Answer: No — unless specifically designed for it, using a tower as a loading bay exceeds its design intent and risks overloading and instability

Standard tower scaffolds are not designed to withstand the dynamic loads from hoisting operations. The swinging and impact loads from hoisted materials can exceed the platform's capacity and the dynamic forces can cause the tower to overturn.

What should an operative do if unauthorised modifications have been made to a tower scaffold?

Answer: Do not use the tower, report the modifications, and have a competent person assess and rectify the situation

Unauthorised modifications (removed braces, added platforms, unofficial ties) may compromise the tower's structural integrity. The tower must not be used until a competent person has assessed the modifications and either approved or reversed them.

What is the correct way to handle scaffold boards and platforms during windy conditions?

Answer: Ensure all wind locks are engaged, remove any loose boards, and consider dismantling the platform if high winds are forecast

All platform wind locks must be fully engaged to prevent boards from being lifted by wind. Loose boards can become dangerous projectiles. If high winds are forecast and the tower will be unattended, consider removing or securing all loose items and reducing the tower height.
